Technology accelerates the liberation of resources, yes, but it is not creating them; it is finding them and using them up, then looking for the energy to repeat the process with progressively poorer materials, moving them faster, making them into smaller, less recoverable fragments for a diminishing proportion of the earth's growing masses of people. Wisely used, technology should enable us to do more with less, but the change to such use has barely begun. We have not yet learned to ask,before undertaking a vast project, what does it cost the earth?
